A frame and suspension assembly for a vehicle can include a pair of frame members configured to support a load input thereto, a final drive structure connected to each of the frame members such that the final drive assembly is configured to input a load to the frame members, and a stabilizer bar mounted to each of the frame members and extending in a traverse direction of the vehicle over a top of the final drive structure.

A suspension device for a non-steered driving wheel including a wheel carrier having an in-wheel motor incorporated therein for driving the driving wheel, and a suspension arm pivotally supported on a vehicle body and connected to the wheel carrier by a connecting structure. The connecting structure includes a plate member fixed to the wheel carrier by fastening and a pair of elastic bushing devices attached to the plate member. The suspension arm has an open cross sectional portions for receiving portions of the plate member and the elastic bushing devices, and the elastic bushing devices are fixed to the open cross sectional portions at both ends.

A suspension device for a non-steered driving wheel in which an in-wheel motor for driving the driving wheel is incorporated in a wheel carrier and which includes suspension arm pivotally supported on a vehicle body at one end and connected at the other end to the wheel carrier via at least two elastic bushing devices. A principal elastic axis which is determined by the at least two elastic bushing devices and extends vertically passes through a grounding area of the driving wheel.

A suspension system for a vehicle is provided. The vehicle comprises a pair of rear wheels and a prop-shaft. A rear drive unit is operably coupled between the prop-shaft and the pair of rear wheels, the rear drive unit being configured to transmit torque from the prop-shaft to the pair of rear wheels. A twist-beam structure is provided having a first trailing arm and a second trailing arm. Each of the trailing arms is operably coupled to one of the pair of rear wheels. The twist-beam structure further comprising a curved beam member extending between the trailing arms, the curved beam member having a center portion disposed offset from the prop-shaft. A Watt linkage includes a first link coupled to the first trailing arm and a second link coupled to the second trailing arm.

A suspension assembly and method of use is provided. The suspension is for an axle on a trailer or other vehicle. The suspension assembly has a cross support member connected with or integrally formed with a hanger bracket at the first end of the cross support member. A trailing beam is connected to the hanger bracket. The trailing beam and a mount are coupled with a load air bag and a lift air bag, with the bags located on each respective side of a pivot axis for the trailing beam. This establishes a teeter-totter configuration of the suspension assembly allowing independent wheel travel side-to-side of the suspension assembly.
